Patented Oct. 21, 1930 UNITED STATES PATENT} OFFICE WESLEY JORDAN, OF SOUTH BEND, INDIANA, ASSIGNOR TO SbUTH BEND BAIT COM- PANY, OF SOUTH BEND, INDIANA ARCHERY Bow Application filed August 4, 1928. Serial No. 297,531.

The invention relates to archery bows, and

has for its object to provide a device of this this character having a laminated bow leaf or belly, and having a back made of triangular strips of bamboo glued or otherwise secured to the belly and to each other, and having also suitably secured to the bow at the center of the belly thereof a stiffener or brace preferably formed of some hard wood.

A further object is to provide a device of this character which is so constructed that the nodules or joints of the bamboo are in staggered relation to prevent weak spots in the bow and to give the maximum of strength.

With the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the in vention.

In the drawings:

Figure 1 is a side elevation of the bow.

Figure 2 is a cross sectional view of the bow taken on line 2-2 of Figure 1.

' Figure 3 is a cross sectional view of the bow taken on line 33 of Figure 1.

Figure 4 is a side view of the laminated belly of the bow showing the manner in which the nodules are staggered.

Figure 5 is a cross sectional view of a modified construction of the bow.

Referring to the drawing, the numeral 1 designates the bow leaf or belly of the bow, which is of laminated construction, being made of thin laminations or strips 2 of fibrous material, preferably bamboo, secured together by means of glue or other suitable adhesive.

The strips 2 are secured together side to side with the greater cross sectional dimension disposed parallel to the line of draft of the bow, which construction results in providing the bow with great strength and compressive resistance, and greatly increases the power of the return stroke of the bow. ln making this laminated structure the nodules or joints 8 of the bamboo are staggered, as shown in Figure 4, in order that there be no weak spots in the construction. The outer side of the belly is made fiat as is the center of the inner side thereof, and the outer ends of the inner side of the belly are rounded. The inner and outer sides of the belly gradually taper toward the ends so that the cross sectional area at the center thereof is greater than that at the ends, which causes the resilience of the bow to increase at the ends thereof.

Secured to the fiat outer side of the belly 1 of the bow by means of glue or other adhesive, is the back 3. The back 3 is formed of strips 4 of bamboo or other suitable fibrous material, preferably triangular in cross section, which are adlies ively secured together.

The sides of the bziclfpreferably taper upwardly and the top of the back is preferably flat. The nodules of the bamboo in the back are also staggered for the same reason and in the same manner as those in the belly of the bow. This back so constructed and secure-d to the bow further increases the compressive strength of the bow and the return stroke of the bow.

To the inner side of the bow at the central flat portion thereof is adhesively secured a stiffener or brace 5 which is preferably made of some hard wood such as hickory, walnut, etc. The brace acts to stiffen the center of the bow and to impart to the ends thereof a. relatively greater resilience and a consequent greater effectiveness to the bow as a whole, causing the ends to move with a somewhat whip-like action. The exposed portion of the brace is preferably made rounded so that the entire inner side of the how when assembled is rounded.

At the ends of the bow'are secured in any suitable manner the tips 6, preferably made said strips being adhes ively secured together, of metal, which provide suitable means saldportlpns of the joints bemg out or regiswhereby the bow string 7 may be secured to tratlon Wliih each other.

the bow in proper position.

It has been found that an archery bow of the above construction and made of bamboo is particularly advantageous in that it has much greater strength than a bow whose belly and back are made of single pieces of wood, due to the use and position of the wood enhancing the normally great inherent strength of the bamboo. Other advantages of this bow are uniformity of strength and resilience due to the laminated structure, a bow of lighter weight than those of hard woods, a smooth powerful return stroke resulting from the use of the bamboo, and the elimination of the kick common in bows of hard wood construction.

he invention having been set forth, what is claimed as new and useful is:

. 1. An archery bow comprising a laminated bamboo belly, the greater cross sectional dimension of said laminations being disposed parallel to the line of draft of the bow, a back adhesively secured to said belly, and a brace adhesively secured to the center of the inner face of said belly.

2. An archery bow comprislng a laminated I bamboo belly, the greater cross sectional dimension of the laminations being disposed parallel to the line of draft of the bow, and a reinforcing member secured to the inner side of the body intermediate the ends thereof.

4. An archery bow having a laminated body formed from bamboo, the greater cross sectional dimension of the laminations being gisposed parallel to the line of draft of the 5. A laminated bow formed from strips of bamboo, said strips having their greater cross sectional dimension parallel to the line of draft of the bow, said bamboo strips including portions of the joints of the piece of bamboo from which they are formed, said strips being secured together adhesively, said portions of thejoints of the strips being out of registration, whereby the strips are braced by adjacent strips at the joint portions.

6. An archery bow having a laminated body, the greater cross sectional dimension of the laminations being disposed parallel to the draft of the bow, said laminations being formed from bamboo strips having portions of the original joints of the bamboo,

In testimony whereof I afiix my signature.
